When applied to a triangle a dilation with a positive scale factor does not preserve what?
length
Does dilation change the shape?
Geometric dilation (size change, typically expansion) does not change the shape of a figure, or its center location, only the size.
What is center of gravity of a triangle?
The center of gravity of a triangle is its centroid. The centroid of a triangle is the intersection of the three medians.
What is the center of mass of an equilateral triangle?
Center of mass of an equilateral triangle is located at its geometric center (centroid).
Which lines do you draw to find the center of a circle inscribed in a triangle?
In geometry, the incircle or inscribed circle of a triangle is the largest circle contained in the triangle; it touches (is tangent to) the three sides.The center of the incircle is called the triangle's incenter.The center of the incircle can be found as the intersection of the three internal angle bisectors.You draw three lines. Each line from one triangle head point to the opposite triangle side and bisecting the angle. These three lines will intersect in one point which is the circle center.
Triangle ABC below will be dilated with the origin as the center of dilation and scale factor of 1/2?
0.5
If Triangle R'S'T' has sides of 3 cm 4 cm and 5 cm. And triangle RST has sides of 12 cm 16 cm and 25 cm. what is the dilation of the triangles?
The 1st is a right angle triangle and the 2nd is a scalene triangle.
Every dilation has a?
Center and Scale Factor....

The center of gravity of a triangle solid with uniform thickness and density is at the intersection of the of the triangle?
The center of gravity of a triangle can be found by adjusting the thickness. You also need to find the density at the intersection.
What are the coordinates for an image on a dilation with a center at the origin?
it is nothing
A photographer knows that the center of a camera lens acts as a center of dilation, where the image of an object forms behind the lens.Is the scale factor for this dilation negative or positive?
Negative
What are the coordinates of the vertices of triangle a'b'c' after triangle ABC is dilated using a scaling factor of 3?
Find the coordinates of the vertices of triangle a'b'c' after triangle ABC is dilated using the given scale factor then graph triangle ABC and its dilation A (1,1) B(1,3) C(3,1) scale factor 3
When applied to a triangle a dilation with a positive scale factor does not preserve to what?
The perimeter to area ratio.
How do you find the in-center of a triangle?
To find the incenter of a triangle, you bisect two or more of the angles. The one spot where these two or more angles meet is called the incenter.
